WASHBOILER.

SPECIFICATION formingpart of Letters Patent No. 611,804, dated October 4, 1898. Application filed January 18, 1897. satn No. 619,627. (No model.)

To all whom it may concern:

Be it known that I, LAURITZ ANDERSON,

a citizen of the United States, residing at Quincy, Adams county, State of Illinois, have invented a certain new and useful Improvement in Steam-Washboilers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to that class of steamwashboilers in which a fountain is provided within the boiler for the purpose of conveying the steam from the base of the boiler to its top and creating a continuous circulation through the clothes in the boiler by means of the recurring passage of steam up through the fountain, through the clothes, and back to the fountain again.

The object of my invention is to provide a steam-fountain of a construction that will distribute the steam evenly throughout the boiler and return it to the fountain at the base of the boiler next to the boiler-wall, such location being the coolest portion of the boiler, causing the steam to more readily condense before entering the fountain at its lowermost portion.

My invention also relates to other features of construction that will be hereinafter fully set forth; and my invention consists in features of novelty hereinafter fully described and claimed.

Referring to the drawings, Figure I illustrates a vertical section taken on line I I, Fig. II. Fig. II is an exterior elevation of my improved boiler. Fig. III is an elevation of the steam-fountain. Fig. IV is a detail view of the central portion of the corrugated bottom of the boiler.

In the drawings, 1 designates the side wall of the boiler, and 2 its bottom. The bottom 2 is formed with a series of circular concentriccorrugations for the purpose of increasing its heat-contacting surface.

3 designates centering guide blocks for seating the steam-fountain located in the bottom of the boiler against its exterior wall, in which position the said blocks are secured by any suitable means.

The steam-fountain has a vertical rim 4 and a dome imperforate on the exterior of the stand-pipe 7, that forms a false bottom upon which the clothes are supported. The rim 4 is formed with an annular inner beading 4. The dome is formed with a peripheral vertical flange 5, by which it caps the rim 4. In the rim 4, near its base, over the beading 4, are a number of inlet-ports 6, through which the condensed water entersthe fountain to be again heated to produce steam that ascends through perforations 8 in the center of the dome 5 into the stand-pipe 7. On the inte rior of the rim 4, over the inlet-ports 6 and the beading 4, are overhanging guards 6, that break the flow 0f the water and steam through the openings 6, inasmuch as guards form stops that prevent the ready exit of the water or steam from the interior of the fountain.

The central portion of the dome 5, in which the perforations 8 are formed, also provides a support for soap, which will there receive the full impact of steam, producing suds that will be conveyed upward through the standpipe 7 and out and into the clothes. On the upper end of the stand-pipe 7 is a fluted and perforated conical cap 9, the wall of which inclines in adownwardly direction, over and through which wall the steam passes, by this means evenly distributing the steam throughout the interior of the boiler. The perforated cap 9 is secured to the stand-pipe by an annular flange 9.

1O designates the conical boiler-cover, to the interior of the dome of which is secured a conical breaker 11, that hangs pendent and spreads the steam outward in an even man ner around the stand-pipe and onto the cap 9, thereby causing all of the clothes to receive an evenly-divided quantity of steam.

of the boiler are a number of perforations 13. Exterior of the boiler is an annular rim 12, connected to the boiler at a point considerably beneath said openings 13. The purpose of this rim 12 is to provide a receptacle for a quantity of water beneath the openings 13, with which water the steam on escaping through the openings .comes in contact with the water in said receptacle, and owing to said water being of a lower temperature the steam is caused to condense on coming in contact therewith. The openings 13 permit of the return of Water to the boiler when sufficient steam has condensed to reach above the level of the base of the openings. The guide-blocks 3 are provided for the purpose of centering the rim at of the fountain, thereby equally dividing the space surrounding said rim and affording an opportunity for the ingress of water around the entire rim. The dome 5 being imperforate exterior of the stand-pipe, the water to enter the fountain must necessarily pass to the wall of the boiler, the coolest portion thereof, Where its temperature is most readily lowered, by reason of which it more readily enters the fountain.

I claim as my invention- 1. A steam-Wash boiler comprising a body, a cover, a pendent conical breaker located Within the apex of the cover, and a fountain having a stand-pipe provided with an open upper end in close proximity to and surrounding the point of the conical breaker and the LAURITZ ANDERSON.
